Title: Manufacture of semiconductor device
Inventor: HASHIMI KAZUO
IPC: H01L29/78
Filed: 1989-05-31
Abstract: PURPOSE:To more enlarge the part where a gate electrode and a drain diffusion layer overlap each other so as to obtain a semiconductor device which can suppress electric field concentration by providing a mask at the gate electrode formation part of a polycrystalline silicon for gate electrode formation, and successively performing thermal oxidation. CONSTITUTION:A semiconductor for gate electrode, for example, polycrystalline silicon 13a is stacked on a gate oxide film 12, and thereon a mask 14 of silicon nitride film to become a mask in thermal oxidation process is formed. Next, when thermal oxidation process is done, the polysilicon excluding the mask 14 becomes an oxide layer 13b. Next, when the Si3N4 film 14 is removed and the SiO2 layer 13b is removed by dry etching, a gate electrode 13 in the shape of downward slowly tapering can be obtained. Successively, ions of n-type impurities are implanted so as to form an n-type region 15. The profiles of these source and drain diffusion layers 15 reflect the shape of the gate electrode 13, and take downward slowly inclined shapes, whereby electric field concentration disappears, and creation of hot carriers is prevented.
